joomla getMailer() not working as expected - php

Question

im trying to use joomla mailer to send emails but it doesent work, any suggestions? what am i missing? i've searched around the web and SO, but it didnt help.
the only error i get is 500, and i cant understand why...
this is the actual code:
<?php
//framework joomla
define( '_JEXEC', 1 );
define( 'DS', DIRECTORY_SEPARATOR );
define( 'JPATH_BASE', realpath(dirname(__FILE__) . "/../"));
require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' );
require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' );
require_once ( JPATH_BASE .DS.'libraries'.DS.'joomla'.DS.'factory.php' );
$mainframe =& JFactory::getApplication('site');
//get vars
$session =& JFactory::getSession();
$num1 = $session->get('variable1');
$num2 = $session->get('variable2');
$val= $session->get('variable3');
$uq= $session->get('unique');
$sendto= $session->get('mail');
//mail
$mailer =& JFactory::getMailer();
$mailer->setSender('some1#domain.com');
$recipient = array($sendto, 'some1else#domain.com');
$mailer->addRecipient($recipient);
$body = '<h2>sometext</h2>'
. '<div>sometext</div>'
. '<div> blabla' echo $num1 'blabla </div>'
. '<div> texttext' echo $num2 'texet </div>'
. '<div> texttext' echo $val 'text </div>';
$mailer->isHTML(true);
$mailer->Encoding = 'base64';
$mailer->setBody($body);
$mailer->AddEmbeddedImage("$uq".".gif", "image_0", "", "base64", "image/gif");
$mailer->addAttachment("$uq".".gif");
//send
$send =& $mailer->Send();
if ( $send !== true ) {
//Elimina .gif
$mask = "*.gif";
array_map( "unlink", glob( $mask ) );
unset($mailer);
echo 'error: ' . $send->message;
} else {
unset($mailer);
//Elimina .gif
$mask = "*.gif";
array_map( "unlink", glob( $mask ) );
echo 'done';
}
?>
forgot to add specs about the platform:
PHP Version 5.3.22
Joomla! Version 2.5.9
if you need any other info just ask.
update:
i tried another joomla! version, a simplified version of the code without variables and with a single email, plain text emails... nothing seems to work.
internal server error (500) with a blank error log... (wierd, but the installation it's inside a subdirectory with many other installation, and my webhosting allow me to see only the "root" log, so i think this is the problem of the blank error log...)

Answer 1

Not quite sure whether this is the root of your problem. But $mail->setSender() accepts an array. Example : $mail->setSender(array('SENDER EMAIL', 'SENDER NAME'));
AND
$mail->addRecipient() accepts a string OR an array. Use an array if you are sending the email to multiple recipients and the string when you are sending the email to only 1 recipient.
Hope this helps

Answer 2

ok, solved!
this might help someone else so, here is how:
$config =& JFactory::getConfig();
this line grabs the email configuration of Joomla, without this Jmail will not send emails.
//body email
$body .= "<h2>Texttext</h2>" . "\n";
$body .= "<div>TexttextTexttextTexttext" . $blockh . " Texttext " . $blockd . "\n";
$body .= "<div> TexttextTexttext <span> " . $num1 . " </span> Texttext </div>" . "\n";
$body .= "<div>TexttextTexttextTexttext <span> " . $val . " </span> Texttext </div>";
previus concatenation of the body was not working, it seems that double quotes are needed to work...
$mailer->isHTML();
the "true" inside is not necessary since true is the default value..

Answer 3

In answer to KentaS comment of
previus concatenation of the body was not working, it seems that double quotes are needed to work...
It has nothing to do with single or double quotes.
In your original post you had:
$body = '<h2>sometext</h2>'
. '<div>sometext</div>'
. '<div> blabla' echo $num1 'blabla </div>'
. '<div> texttext' echo $num2 'texet </div>'
. '<div> texttext' echo $val 'text </div>';
the part:
'<div> blabla' echo $num1 'blabla </div>'
causes a syntax error (string, followed, without concatenation, by a call to "echo", followed, without concatenation, by a string...!
Somthing which works with single quotes:
$body = '<h2>sometext</h2>'
. '<div>sometext</div>'
. '<div> blabla' . $num1 . 'blabla </div>'
. '<div> texttext' . $num2 . 'texet </div>'
. '<div> texttext' . $val . 'text </div>';
And with double quotes you can do even shorter:
$body = "<h2>sometext</h2>"
. "<div>sometext</div>"
. "<div> blabla $num1 blabla </div>"
. "<div> texttext $num2 texet </div>"
. "<div> texttext $val text </div>";
